According to a Reddit user who replied to the original post on subreddit There is another fake wall situated near the doorway that was featured in the original video. The post also included a photo of it , along with Elden Ring Runes some spoiler-y information about the location of the wall that you can read here. The fake wall is able to be destroyed similarly by a few hits from any weapon you want to use. However, it's not as demanding as many hits, based on the stats you have, as some players claim.

To clarify: The idea of fake, secret walls isn't the thing that got Elden Ring players excited. Strange walls that conceal secrets are an integral aspect in Elden Ring. The so-called "illusory wall" are known and well-documented. What is unique about the (and another similar) hidden wall so bizarre is the fact that it doesn't operate as other illusory wall in the game, and doesn't have the same sound cues disappearing, returning after you are at the Site of Grace, and it takes a plethora of hits to unlock. Although initially, the video led to the conclusion that the door could have been a deliberate design however, some players and experts are now suggesting that the wall could be an error or a mistake made within the game's code by the developers.

The well-known Dark Souls hacker Zullie seemingly confirmed this idea--that it was an error made by the developers on March 18 in a brief Twitter post. The hackers explained that after examining the game's files and exploring the fake wall and claiming to have seen the door's display shows 9999 hit points. It's similar to the unbreakable objects found in Dark Souls having 999 HP. But, these items also have 999 defenses which means they do not take the brunt of buy Elden Ring Runes any attack. They are only broken by in-game triggers or events crafted by the developers.
